IMPROVEMENT IN EARTH-CLOSETS.

Specification forming part of Letters Patent No. 219,767, dated September Y16, 1879; application iiled January 28, 1879.

construction and arrangement of devices for operating the earth-carrying apron by the ralslng and lowering of the lid of the seat,

- whereby economy of space is secured, andthe apparatus is adapted to be used`either in connection with a stationary closet or a vault out of doors, or with a portable closet or commode used in the house. n

The accompanying drawings illustrate the manner of carrying out the invention.

Figure 1 is a side view of an apparatus embodying my improvements, being shown as applied to a box-or commode and in position Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a view looking upward; and Fig. 4 a top view.

Similar letters of reference indicate corresponding parts.

A represents a connnode, box, or casing, of any suitable description, or a portion of a vault or closet, with the apparatus applied thereto. B B represent horizontal ways or guides, in which the apron-carrying frame works. C represents the apron-carryin g frame provided with two rollers, D D, and an apron, E. Gl G2 are stationary bars, having their ends attached to the' ways B B, and lying, respectively, above the lower portion and below the upper portion of the apron E, and H1 H2 are cams whichbear against the apron opposi'te the bars G1 G2 respectively. These parts are similar in their construction, arrangement, and operation to the similar parts shown in my patent of May 21, 1878, aforesaid.

For operating the apron-frame I employ the following devices: To the guard Cz of the apron-frame is attached a clevis, J, to which is pivoted oneend of a connecting link or bar, K, the other end of which is pivoted to one end of a lever, L, which has its fulcrum on a plate, l, attached to one of the ways B. The clevis J, link or bar K, and lever L all work in a horizontal plane. The other end of the lever L is connected by a link or bar, M, to an arm,N, which projects from the seat lid or cover R. Said arm may be the continuation of a strip or bar of metal, attached to the edge of the lid'or cover, and may also form part of one of the hinges.

Whenthe lid or cover R is raised, the arm N and link M draw one end of they lever L forward and the other end backward, so as to move the apron and its frame back from under the seat, and when the lid or cover is lowered a reverse movement of the apron takes place.

The dry earth is deposited in thel same nanner as described in my former patent aforesaid, the earth being received on the apron E from a hopper, P, of any suitable construction.

By thus arranging the parts in a horizontal plane, economy of space is secured,.and the apparatus, when folded, occupies less space than when the parts Work in a vertical plane, as in my former patent. Moreover, vthe apparatus is rendered more easily portable, and may be readily applied to an out-door vault or closet, or to an indoor commode, box, or casing.

In order to prevent the escape of dust or odor from the vault, commode, or other space beneath the seat, I employ a swinging door, which may be in one or more parts, as may be preferred. As here shown, it is made in two parts, T T, each of which is hinged to the un der side of the seat Q, so as to swing downward out of the way, or upward to cover the opening in the seat.

For closing the doors T or swinging them upward. I employ two devices, each of which consists of a two-sided inclined plane, or the junction of two inclined planes, side by side, terminating in a point, and somewhat resembling the half of a spear-head. These inclined planes S S are carried by the guard C2 of the apron-frame, with their points extending toward the front of the apparatus.

When the seat-lid R is raised, and the apron- 1. The combination, with the seat-lid and the apron-frame, of the clevis J, link or bar K, lever L, link or bar M, and arm N, arranged and operating substantially as herein described.

2. The inclined planes S, carried by the apron-frame, in combination with the door or doors T, substantially as and for the purpose herein described.
